Roserio, Italy

Half a postmark. A bit of a challenge. The clue was CMP which is an acronym for Centro di Meccanizzazione Postale: a sorting center. So I just had to find a sorting center with a name that ended in "serio". This mail was processed at the Milano Roserio CMP in the district of Roserio on the north western edge of the city of Milan. The stamp on the left is from a 2022 Philately Day set with the theme "go back to writing". And on the right, a stamp from 2019 commemorating the "80th Anniversary of the National Fire Brigade".
